Amazon Redshift will no longer support the creation of new Python UDFs starting Patch 198. Existing Python UDFs will continue to function until June 30, 2026. For more information, see the [ blog post ](https://amazonaws-china.com/blogs/big-data/amazon-redshift-python-user-defined-functions-will-reach-end-of-support-after-june-30-2026/). 

# Create a zero-ETL integration with applications
<a name="zero-etl-setting-up.create-integration-glue"></a>

In this step, you create a zero-ETL integration with applications with Amazon Redshift.

**To create a zero-ETL integration with applications with Amazon Redshift**

1. From the Amazon Redshift console: [Create and configure a target Amazon Redshift data warehouse](zero-etl-setting-up.rs-data-warehouse.md). 
   + From the Amazon CLI or Amazon Redshift console: [Turn on case sensitivity for your data warehouse](zero-etl-setting-up.case-sensitivity.md).
   + From the Amazon Redshift console: [Configure authorization for your Amazon Redshift data warehouse](zero-etl-using.redshift-iam.md).

1. From the Amazon Glue console: [Creating an integration](https://docs.amazonaws.cn/glue/latest/dg/zero-etl-common-integration-tasks.html#zero-etl-creating) as described in the *Amazon Glue Developer Guide*.

1. After the destination database has been created and data starts replicating, you can query and create materialized data for your replicated data. For more information, see [Querying replicated data in Amazon Redshift](zero-etl-using.querying-and-creating-materialized-views.md).
